Apple on Tuesday named insider Sabih Khan as its chief operating officer, taking over from Jeff Williams, as part of a long-planned succession.

Apple COO Jeff Williams is retiring after 27 years. His exit marks another recent major leadership shift at the company.

Sabih Khan, an Indian-origin techie, has been appointed as Apple’s new chief operating officer (COO). The Moradabad-born executive has been part of the tech giant for nearly 30 years, and will succeed Jeff Williams.
